Hi there, fellow CBM fans! I've had my C64 for about 5 years now, even though I got myself an A500 last year, I didn't have the heart to part with my trusty '64. But now I have a girlfriend in the states, and seeing as how I'm living in Europe, using Pal, I was wondering if it is possible to use a European C64 in the states? I know that you need a special plug to convert the 110 volts to 220, but other than that, will the computer work properly and normally? The purpose is to hook it up with a modem - how fast can the C64 do this (how many baud), and which modems are a good buy? Replies by e-mail, please. Thanks in advance, Asger Hoegsted -- ---------------------------------------------------------------------- -- Asger Hoegsted, Comp.

No, you'll also need to send a PAL display (television or monitor). -- Geoffrey Welsh - Operator, Izot's Swamp BBS (FidoNet 1:221/171) root@zswamp.uucp or ..uunet!watmath!xenitec!zswamp!root 602-66 Mooregate Crescent, Kitchener, ON, N2M 5E6 Canada (519)741-9553 "He who claims to know everything can't possibly know much" -me

Also, I was told that it may not be enough to change the voltage - that the frequency would still be the same, and that that would make the computer unable to function. Is this true?

No, I'm afraid not. The jumper affects the clock divisor (by the look of the schematic), but it doesn't change the fundamental operations of the components (some of which may even be PAL-specific). By the time you replaced enough components to make a PAL 64 work on an NTSC monitor, it would have been cheaper to buy a new North American C64! >Also, I was told that it may not be enough to change the >voltage - that the >frequency would still be the same, and that that would make >the computer >unable to function. >Is this true? No, that's not true. The internal clock frequency is set by the crystal in the computer, and that will remain unchanged. The one thing that will be affected is the time-of-day clock in the CIA (not used by the C64 operating system, but it is used by lots of software); however, bit 7 of each CIA's control register A will permit you to set it to count 50 or 60 cycles, and that should solve the problem in most cases. Matthew Desmond - the fellow who write DesTerm and a friend of mine - has a British C64, 1571, and a PAL TV all connected to a voltage converter. They work fine (well, the TV occasionally glitches... but I'm not sure if that's a line frequency problem or just that it's in need of repair!)
